# std::codecvt<InternT,ExternT,StateT>::~codecvt

From cppreference.com
< cpp‎ | locale‎ | codecvt

Defined in header `<locale>` |  |
protected: ~codecvt(); |  |

Destructs a std::codecvt facet. This destructor is protected and virtual (due to base class destructor being virtual). An object of type std::codecvt, like most facets, can only be destroyed when the last std::locale object that implements this facet goes out of scope or if a user-defined class is derived from std::codecvt and implements a public destructor.

### Example

Run this code

    #include <iostream>
    #include <locale>

    struct Destructible_codecvt : public std::codecvt<wchar_t, char, std::mbstate_t>
    {
        Destructible_codecvt(std::size_t refs = 0) : codecvt(refs) {}
        // note: the implicit destructor is public
    };

    int main()
    {
        Destructible_codecvt dc;
        // std::codecvt<wchar_t> c; // compile error: protected destructor
    }
